ELECTRIC SIGNAL.

SPECIFICATION forming part of Letters Patent NO. 427,762, dated May 13, 1890.

Application filed July 10, 1889.

To all whom it may concern;

Be it known that I, JOsEF HAAS, J11, a subject of the Emperor of Austria-Hungary, residing at Vienna, in the Empire of Austria- Hungary, have invent-ed certain new and useful Improvements in Electric Signals; and I do declare the following to be a full, clear, and exact description of the invention.

This invention relates to an improved signaling device for railways, and especially to that class of signaling devices which are operated automatically and by a current of electricity.

The object of my invention is to provide a railway-signal of this kind which is simple in construction and reliable in use.

The invention consists in the construction and combination of parts and details, as will be fully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of my improved electric railwaysignal, the rail being shown in cross-section. Fig. 2 is an end view of the same, parts of the rail being broken out and parts in longitudinal section. Fig. 3 is a plan view of the signal, part of the rail being broken out. Fig. 4 is a detail side view of the rail, showing the circuit-closer in section.

Similar letters of reference indicate correspondin g parts.

The signal-standard A is mounted to turn in the usual manner, and can be operated by a chain A passing over a sprocket-wheel A on said standard. On said standard the hollow signal-disk S is mounted, which is provided with a suitable cap \V, in which the electric-light mechanism is contained, the connecting rods or post K of said electriclamp projecting from the cap 7. An electro magnet 19 is held on a vertical frame F, and adjacent to one end of the same the armature-lever M is pivoted on a standard M, which armature-lever M is provided on its swinging end with a contact-arm .2, that can come in contact with an arm or contactpieee t. The armature M is secured on said 1ever M On the opposite end of the armaturelever M a curved spring-arm F is secured, on which a cam disk or plate E on the standard A can act. The contact-piece t is connected by a wire G with a storage-battery, the other Serial No. 317,101. (No model.)

pole of said storage-battery being connected by a wire 11 with the binding-post K of the lamp, which binding-post is connected by the wire H with the armature-lever M One pole of a battery B is connected by a wire K with one contact-point of a circuit-closer below the rail X, the other contact-piece of said circuitcloser being connected bythe wire J with one end of the wire forming the electro-magnet p, the other end of said electro-magnet coil being connected by the wire C with the ground. The rail X is provided with a vertical aperture in which a pin can work, which projects slightly from the top of the rail and rests on a spring-arm f of a circuit-closer below the rail, which spring-arm f can be pressed down and brought in contact with the other contact-piece f of the circuit-closer.

The operation is as follows: The circuitcloser is located a greater or less distance from the signal, and when the first wheel of the locomotive arrives at said circuit-closer it operates the same, whereby the circuit is closed from the battery B through the wire K, the contacts ff, the wire J, the electro-magnet p, the wire 0, and the ground. Thereby the armature M, which is held by the spring-arm F in the position shown in dotted lines in Fig. 3, is attracted and brought into the position shown in full lines in Fig. I

The arm of the armature-lever M is brought in contact with the contact-piece t and the lamp-circuit is closed, as follows: From the storage-battery through the wire G to the contact-piece i, the arm .2, the armature-lever M the wire H, and the lamp in the signal-disk, and through the wire ll back to the storage-battery. As the signal-disk has a suitable opening closed by colored glass, the signal is lighted up and clearly visible as soon as the train runs on the electric switch, thus indicating to the engineer when he can pass on or when he must step. In case the signal-standard A is turned by means of the chain A the cam-piece E, aetin g on the spring-arm, presses the same sidewise, whereby the armature M is swung from the end of the electro-magnetp and the lam p-eircuit broken.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. In an electric signal, the combination, with a standard, of an electric lamp on the same, a storage-battery or other source of electricity having one pole connected with the electric lamp, an electro-inagnet, an armature for said electroqnagnet, a wire connecting the electric lamp with said armature, a contact-piece connected with the storage-battery, a local battery, conducting-Wires connecting the local battery with the electro-magnet, and a circuit-closer for closingthe circuit of said local battery, substantially as set forth.

2. In an electric signal, the combination, with an electro-magnet, of a local circuit for the same, a pivoted armature-lever having a spring end, a rotary signal-standard, a campiece on said standard adapted to act on said spring end of the armature-lever, an electric nected with thelamp an d said armature-lever,

piece that can form contact with said lover,

a storage-battery connected with said contactpiece, the pivoted lever, and the electric lamp on the standard, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
